Research Report RR:D11-1104

Research Report D11-1104 presents the results of the Interlaboratory Study used to establish the precision and bias statement for ASTM D6844 Standard Test Methods for Silanes used in Rubber Formulations (bis-(triethoxysilylpropyl)sulfanes): Characterization by High Performance Liquid Chromatography (HPLC). The collaborative study included 9 labs who used method D6844 to analyze the elemental sulfur, the average chain length and the relative content of S2-S10 of a (bis-(triethoxysilylpropyl)tetrasulfane sample. Due to the small number of labs only one lab was removed for the elemental sulfur result due to an extreme outlier result. The research report presents summary method performance statistics as well as the measurement data used to calculate results for the study.
